Correct Answer - Option 4 : Assigning different group of channels
When neighboring stations broadcast the same set of channels then it is very common to have interference issues, and hence to avoid interference issues between neighboring stations, it is highly recommended to use a different group of channels
We can use TDM (Time Division Multiplexing) to avoid the interference between the neighboring stations
Time Division Multiplexing:
- Time-division multiplexing (TDM) is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing.
- In Time Division Multiplexing (TDM), the time frame is divided into slots. This technique is used to transmit a signal over a single communication channel, by allotting one slot for each message.
- For separating channels in TDM, it is necessary to use Time slots. For this purpose AND gates are used.
- Time Division Multiplexing (TDM) can be classified into Synchronous TDM and Asynchronous TDM.
